| |  word problem, consecutive integers.
The perimeter of a triangle is 78'. The lengths of the sides are represented by 3 conscutive integers. What are those lengths. I have no idea where to start with this one?????????? 
Thanks in advance! |

The lengths of the sides are represented by 3 conscutive integers. Therefore, the sum of the lengths of the sides (Perimeter) is: 
P is given, so solve for n. | | The following users thank Chop Suey for this useful post: | |  |

Hint: let the length of this triangle be  (you may these choose this concecutive number to be  as well). The second choice give you a nicer computation. | | The following users thank watchmath for this useful post: | | |

Still a bit confused on this one, I came up with an answer of
P= 78 consecutive numbers are 25,26,27 but I am not sure how to put this as an equation. |

I guess what I am asking is my final answer is going to look like this.....
78= 25+(26+1)+(27+2) That just does not look right.  |
